Dang, you guys need to learn how to take care of your phones. They're expensive objects you know, especially if you're using phones like iPhone 5, iPhone 6. Like god damn, everyone who posted in this thread has a cracked phone.
i never dropped my phones if my phone gets damaged its usually cuz someone else used it. I dont use cases cuz they make the phone look bigger and its uncomfortable for the pocket
I have a life proof case too, I drop it ocansionly, it's fine, I slip and drop it on the toilet pipe, CRACK
Not that surprising lifeproof are good 'cause waterproof and slim(but it being that slim-there is always going to be more impact past slim casework)
I use a heavy duty one with gorillaglass for £10 not really ever dropped it but my brother has same and allways drops his from pocket hight and his is fine.
